NEIL OAMPBELL OF BROOKLYN, NEW YORK, ASSIGNOR TO THE BROOKLYN RAILWAYSUPPLY COMPANY, OF SAME PLACE.

SNOW-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 375,338, dated December27, 1887.

Application filed March 24, 1885. Serial No. 159,913. (No model.)

To all whom, it may concern:

Be it known that I, NEIL CAMPBELL, of Brooklyn, in the county of Kingsand State of New York, have invented certain Improvements inSnow-Sweepers, of which the following is a specification.

The present invention relates to that class of sweepers in whichrevolving brooms are employed, which receive their motion from the axlesof the machine by means of bevelgearing. In such machines the bearing ofthe broom-shaft has usually been mounted on or connected with the axleof the machine or car, as illustrated, for example, in the patent of E.A. F. Olmstead, No. 64,695. This causes considerable strain to be thrownon the axle,

which is objectionable. In the patent granted to me May 22, 1877, No.190,956, I show a means of mounting the broom-shaft in a hearingindependent of the car-axle, but this construction is very cumbersomeand has not proved satisfactory.

The object of my present invention is to improve this construction andprovide a satisfactory bearing for the yoke that has in it the bearingsof the broom-shaft, and keeps the gear-wheel thereon engaged with thegearwheel on the car-axle. My invention will be fully describedhereinafter, and its novel features carefully defined in the claims.

The accompanying drawings form a part of this specification, andrepresent what I consider the best means of carrying out the invention.

Figure 1 is a plan in section on the line as m, Fig. 2. Fig. 2 is a sideelevation; and Fig. 3 is a transverse vertical section on the liney Fig.2.

These drawings represent only a single broom-shaft and its driving-axle,with the invention applied thereto, it being understood that theconstruction is the same for both or all the revolving brooms that maybe contained in the machine, there being preferably a specialdriving-axle. for each broom-shaft.

A is the frame or platform of the car or machine, supported, in theusual manner, by suitable pedestals and journal-boxes,upon the axle B,which carries the running-wheels O.

The axle B carries in the position indicated a bevel-wheel, D, whichengages with and imparts motion to the bevel-pinion E, upon one endofthe obliquely-running broom-shaft F, upon which is mounted the broom Gr,(shown only in dotted lines,) and which may be of any ordinary orsuitable construction. The other end of the shaft F is journaled inabox, H, which may be suspended bya rod, I, from the frame A, asindicated, or may be supported in any other suitable manner. The end ofthe shaft F which carries the bevel-pinion E runs in two bearings in theyoke J, as shown, the bevel-pinion E, as well as the bevel-wheel D,being inclosed within the yoke. The latter is supported in the followingmanner:

K is a hanger, of cast-iron, which is firmly bolted to the frame A inexactly such position that its two branches, is, embrace the wheel D,and that the circular rims is at the lower endsv of the branches k arestrictly concentric to the axle-B. The laterally-projecting rims Toserve as bearings or supports for the yoke J, which at this point is ofsuch shape as to half inclose or apply upon said rims the caps j, whichare firmly bolted to the yoke when the latter is brought into position,completing the circle,

so as to hold the yoke firmly in position upon said rims.

In order to facilitate the mounting of the hanger K, the lower ends ofits branches and So the rims 7c are not made continuous, but are cutopen, as shown, so that the hanger may be brought into position andsecured at any time after the running-wheels C and the bevel-wheel D aresecured upon the axle.

In order to prevent that end of the yoke J in which the broom-shaft isjournaled from falling by the yoke turning upon the rims k, a stout rod,L, connected to the yoke at the point shown, is extended upward, and itsup- 0 per extremity rigidly connected to the frame A, thus holding theyoke steady in a horizontal or substantially horizontal position.

I claim as my invention 1. The combination, in a snow-sweeper, of thehanger K, having two branches, 70 k, each provided with a circular rim,7c, cut or open at the bottom, as shown, of the yoke J, provided withparti-circular bearings embracing the rims 7; on the hanger, and withbearingcaps j, substantially as set forth.

2. The combination of the frame A, the axle B and its wheels, thegear-wheel D on said axle, the broom, its shaft F, the gearwheel Ethereon meshing with wheel D, the yoke J, provided with hearings inwhich the broom-shaft is mounted, and with a bearing and bearing-cap, j,whereby it is supported on the hanger, the supporting-rod L, and thesaid hanger K, having two branches, k 7., each provided with a circularrim, k, on which the yoke J is mounted, said rims being concentric withthe axle B, and cut or open, as shown, in order to permit of the passageof the axle in placing the hanger, as set forth.

In witness whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
